Basic Ball Mill Grinding Circuit
A mill consists of a steel shell supported at each end by a hollow trunnion running in a bearing, lined with steel plates, and driven by belt and gears or by motor and gears The mill is set at a slight slope and is fed with finely crushed ore and water through one trunnion When ground fine enough by the load of balls, the pulp is discharged through the other trunnion and run where desired The circuit comprises a SAG mill, 12 m diameter by 61 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones The SAG mill is fitted with a 20 MW gearless drive motor with bidirectional rotational capacityGrinding Circuit an overview ScienceDirect Topics Both model predictions and pilot scale ball mill circuit responses are shown 862 RAS K RAJAMAN! and Joua A HERBST CIRCUIT MODELS concentration is the solids concentration, C5 ME Grinding circuit models have been used for the defined as the mass of solids per unit volume of slurry evaluation (Herbst and Mular, 1980) of alternative Then, the holdup mass within the mill is given by Optimal control of a ball mill grinding circuit—I
